Using the ToSingle(String) method is equivalent to passing value to the Single.Parse(String) method. value is interpreted by using the formatting conventions of the current thread culture.
If you prefer not to handle an exception if the conversion fails, you can call the Single.TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.
